The CHARLY is a warm water rinsing device designed for irrigation of the ear and sinus cavities which provide a maximum level of hygiene safety with an emphasis on simple, comfortable operation. Similar to the 38°C water components, the CHARLY components include a completely autoclavable water filter in addition to the water handle with precision metering valve and flow limiter. The external heating cuff on the stainless steel boiler prevents lime furring of the heating elements and does not require a water outlet.
